ABSTRACT:
An improved retainer for an expansion joint system and a sealing cap for the anchor bolt channel thereof. The retainer channel and the cap have complementary mating profiles in the form of ledges with inclined edges and inwardly offset grooves having sloped bottom surfaces on the retainer channel walls, the cap having laterally projecting upper edge portions defining ledge receiving grooves and sloped bottom edge surfaces whereby entry of the cap into the retainer channel is facilitated by coaction between the sloped bottom surfaces of the cap and the inclined edges of the retainer ledges. The retainer ledges mate with the cap grooves to lock the cap in the retainer. The sloped bottom surfaces of the cap are supported by the sloped bottom surfaces of the retainer grooves and the laterally projecting upper edge portions of the cap are supported by the upper surfaces of the retainer ledges, the surfaces being in sealing engagement.
